Abstract

PURPOSE: To suppress the rise of oil temperature and to compact the structure of a control valve by detachably attaching a specific auxiliary control valve block to a specific main control valve block having the 1st and the 2nd solenoid valves.
CONSTITUTION: A main valve block V1 contains a solenoid valve 13 having a lowering operation position DN to lower a hydraulic cylinder 4 relative to a reaping pretreatment apparatus and a solenoid valve 12 having a lifting operation position UP to lift the hydraulic cylinder 4 an output operation position R to supply hydraulic oil to a 1st auxiliary output port A1 and a neutral operation position N to return the hydraulic oil from pumps P1 and P2 to a tank T. The main valve block V1 is attached with detachable auxiliary control valve blocks V2 and V3 having auxiliary output ports A2, A3, exhaust oil ports B2, B3 and solenoid valves 14, 15 to control the flow of hydraulic oil supplied from input ports I1, I2 and supply the oil to other hydraulic cylinders 7, 9 for the other working machine.
